Description

technical field

[0001] The invention belongs to the technical field of temperature relay detection, in particular to a temperature relay test board based on a single-chip microcomputer and a control method thereof. Background technique

[0002] At present, as a non-electrical control temperature relay, it is widely used in industrial control, information industry, household appliances, national defense industry and other fields. Instantaneous disc bimetal temperature relays are used the most due to their large load current, simple structure, low cost and reliable operation. If the electrical characteristics such as the operating temperature, recovery temperature and contact resistance of the temperature relay cannot be measured correctly, it will trouble both production and use. According to the provisions of GJB1517-92 "General Specification for Thermostatic Relays", there are three methods for the detection of temperature relays, including liquid measurement method, air m...
